ARTICULATED can CONSTRUCTION.

- Application filed September 10, 1925 Serial Ito. 55,419. i

This invention relates to an articulated car construction. a 7

One object of the invention is to provide a simple, reliable, durable and efiicient articulated car construction whereby car units may be easily connected, whereby said units may have relatively vertical angling movements, whereby said car units maybe properly held spaced with respect to each other and prevented from having relative transverse movements, and whereby each car unit may have free pivotal movement upon a center plate under which the truck bolster may pivot.

Another object is to provide; a side bearing arrangement for articulated car units adapted to permit relative vertical angling movements between said car units and to resist relative transverse movements between said .car units. y t

Another object is to provide an articulated car construction i1(ltl[)te(l1 t0 meet the various requirements under actual operat-' ing conditions.

These and other objects are accomplished by means of the" arrangement shown on the accompanying sheets of drawings,- in which l Figure 1 is a fragmentary top plan view of twp car units connected in accordance with my invention;

' 'it will be noted that my invention is illustrated in connection with an articulated car construction in which there are two car body units which may be represented by the bod bolsters l0 and 11f Formed integrally wit each of said body bolsters is a center bearing member 12, which center bearing membears are centrally longitudinally aligned with respect to the car body units and have their circular bottom portions pivotally arranged with respect to a center plate 13, in turn pivotally mounted upon a central portion of a truck equalizing bolster 14. Each of thecei'iter bearing members 12 is pivota-lly mounted in its own circular'bearin pocket 15 in the center bearing plate 13 an said bearing pockets 15 are centrally ali ned longitudinal of the car body units. en-

er ally speaking, the lower portions of the center bearing members 12 are cylindrical in shape; The upper portion of each is hollow or recessed as shown at 16 for the reception of 'an associated member 17, the

latter of whichis pivot ally connected within its centerbearing member by a pivot pin 18. Each of said pivot pins 18 is supported within bearing portions 19 and 20 of said center bearing members. ()ne of the menubers 17 has laterally extending wings 21 terminating in projections 22 which are received within corresponding pockets23 of I the other member 17. These members 17 are a interconnected at their winged ends by bolts 24 around which springs 25 are mounted.

The tension of the springs is controlled by nuts 26. Accordingly, it will be seen that the members 17 which are 'pivotally:con-- nected to the center bearing members 12 are yieldably interconnected. lihe lnner'iaces arated. from each other as 'best shown in lgures 11o of the projections 22 and the cooperatingl and 2. These members 17 which connect the car units not only separate the same but prevent relative transverse movements therebetween. In this connection, it will be noted that the vertical side walls dfthe projections 22 engage the vertical side walls of' the pockets 23 so that relative lateral movementbetween the members 17 is prevented. As a result of the separator members 17 being interconnected in the manner in which they are, the 'center plate 13 is held against rotation, but the center hearing members 12 may pivot onsaid center bearing plate, and the truck bolster 14 may pivot under said center bearing plate 13.

The truck bolster may be a three-piece bolster similar to that shown in my Patent No. 1,377,706, granted on May 10, 1921, in

which it will be noted that there are twotransverse saddle members 30 formed integrally with the central cross-truck bolster cmember 14, the saddle members 30 being rockably mounted upon two supported associated transverse bolster members 31. \Vhile this truck bolster is for a six-wheel truck, it will be understood that my invention is not limited to a six-wheel truck.

Referring particularly to Figures 6, 7 and 8, it will be noted that the body bolster member 10 is provided with two side bearing-s32 which rest upon side bearing members 33 formed on the other body bolster 11. The side bearing members 32 are housed within pocket portions 34 of the side bearing members 33 at body bolster 11. The body bolster 11 is provided with additional side bearings 35 located just inwardly from the side bearings 33 and therebelow, which rest upon rocker blocks 36 formed in a side bearingrhousing 37 on the truck bolster 14. Tu this way not only is the side bearing load finally transmitted to the truck bolster but also the car body units arefpermitted to angle vertically with respect to each other because of the rocker block arrange ment 36. These rocker bloeks 36 are retained against displacement within the said bearing members 37. The side bearing surface oi bearing 32 may be slightly curved also for ments.

By means of this simple construction, the

car body units are held spaced a art, are

permittingfvertlcal anghng movepermittedto have relative vertica angling movements but'are prevented from having relative transverse movements; said car body units may pivot upon the center plate which they have in common and the truck may pivot at the said center plate, all of the parts cooperating in a manner to meet the variousrequirements under actual service conditions.

Ttis my intention to cover all modifications of the invention falling within the spirit and scope of the'following claims.

7 r rcaaaaa nal alignment, a truck bolster, and a center plate pivotally mounted on said bolster and having oppositely arranged bearing portions pivotally associated with respect to each of said center bearing members to form a flexible operating arrangement.

In an articulated car construction, the combination oi two car body units, a center bearing member on each unit, a truck bolster, a center plate pivotally mounted on said. bolster and pivotally arranged with respect to cachet said center bearing members to form a flexible operating arrangement, and means connecting said center bearing members, acting as a separator between said car body units to resist relative transverse nmvements between said units and to cause pivotal action between said center plate and bolster in taking, curves during car operation.
